You might also consider posting a summary of how the various advice you received worked out for you, after conversation has died down. I try to wrap up each thread I start with a summary of the suggestions I got, and how they worked out. An example is How to Calculate Memory Needs?.

Doing it all in one post near the end avoids clutter, and helps people get an idea of what to expect from the other nodes in the thread without having to read them all first.

I agree - I think considered responses from the person asking the q can really add value to a thread. I suppose I just wanted a labour-saving way to tell the other authors I'd done that... but I think particle's suggestion covers that, actually, without the need for any fancy stuff. /me goes off to send a thankyou /msg to particle
